To all whom, it mag/concern:

\ Be it known that I, WILLIAM E. JOHNSON; a

i citizen'of the United States of America, residing at Coon Rapids, inthe county of Car- *5 roll,' and State of Iowa, have invented a new anduseful Reversible Door-Latch for Sliding Doors, of which the following'is a speciea-- tion.

The objects of my invention are toproduce.

I0 a simple, cheap and durable device adapted to be attached to slidingdoors and capable of being latchedor unlatched from yeither side of thedoor and adapted to be locked from the inside, and my object is furtherto provide a` I5 latch and lock that may be applied to either side of adoor."

With these objects in view my invention consists in certain details intheconstruction,

arrangement and combination of the various- 2 0 parts of the device ashereinafter set forth,

. 3 the reference letter A is used to designate a sliding door and A alike door. adaptedv to meet the inner edge ofthe rst.

B designates the lock frame preferably coinposed of metal; plates andprovided. with B? whereby it "maybe secured to a door. C is a shaftextended transversely through i lsaidframe and of a length adaptingA itto be passedV through an opening in the dooi` A and #4b having a knob orhandle C2 secured thereto whereby it maybe turned.- D designates a leverfixed tothe shaft C within the frame having its upper end bifur-v catedand ahandle D2 formed on its lower end I `45 to project belowthe frameof the latchfto pro# vide means whereby the latch may be operated. .l

The'latch proper designated by the refer ence letterF is extendedtransversely through 5 the frame and is provided with a hook F2 on eachend sothat when 'thel latch is reversed either end may be used.

Trame, a latch having a hook. formedv on its designates a device adaptedto be'seeured `to astationary sZ'pport'or toa doorl in prox= imityytothe edg' of the. door to which the 55 latch is attached and is adaptedto admit the sliding latch and holdl .it therein until it is elevatedand drawn backwardly. J designates aguide consisting of astraigh t rod.extended transversely through the frame 6.9 of thedevice and above thelatch Fi near its rear end. This guide is positioned so as to" hold therear end vof the latch' downward when its central portion is elevatedbyturning the knob' and thereby elevate the forward 5g lend so as toraiseit above the device that'y rthehook engages and allow it to be loweredto engage said device when in an extended' position. An opening .l2 isprovided at the other side ofthe center of the latch frame to. 7b

also through the lever D so as to prevent as y' movement ofthe latch.Y'A similar -bore K3 is .provided at the opposite 'side ofthe latchframe to be used wheny the device is `employed` Having thus described myinvention, what So I claim as new therein, and desire to'secure byLettersv latent .of the United States thereforis o l. An improved latchfor sliding doors, comi prising a suitable frame adapted' to be se- 85cured to a sliding doo-r, a shaft extended through `said frame anddoor', aknob on its outer end, a lever fixed to saidjrock shaft A( withits inner end projecting below the latch 9.0 forward endextendedhorizontally through the device and pivotally attached 'to the up. perend of said leverjsomedistance above .its pivotal point,- a rod extendedvtransversely through the frame of the deviceabove -the rear end of thelatch for the purposes stated and a device secured to a stationaryupright andadapted to be engaged by said latch substantially as and forthe purposes stated.
